Title:
液晶を用いた電気光学素子、特にスイッチを形成する素子
Document Type and Number:
Japanese Patent JP2004521390
Kind Code:
A
Abstract:
The present invention provides an electro-optical device, characterized in that it comprises two plane optical substrates ( 100 ) each having at least one optical waveguide ( 110 ), and a nematic liquid crystal ( 200 ) inserted between them, in which the liquid crystal ( 200 ) is split into two separate active zones ( 210, 220 ) serving to control coupling/decoupling of a respective one of the TE and TM polarizations of a light signal injected into the waveguides ( 110 ).
